Original application `filed December 12, 1914, Serial No. 876,949. Divided and this application led April 29',

, 1918. Serial No. 231,514. Y A

To all fui/tom t may concern.'

Be it known that ALBERT A. MACLEOD, a citizen of the United States, residing at Swampscott, in the county ofV Essex and State of Nlassachusetts, and LOUIS BROWN, late of Beverly, in the county'of- Essex and State of Massachusetts, deceased,

invented certain .Improvements in V/Vork-v Supports, or which the following'description, in connection with the accompanying drawings, is a speciiication, likev reference characters on the'drawings indicating like parts in -the several figures. Y y

T hisinvention relates to means for supporting the heel portions oflasts and par-v ticularly to means for preventing injury to the uppers of shoes when placed upon such supports.' f i j Iny the operation of many Shoe machines, the shoe to be 4treated is mounted upon a last which is-located bythe lastv pin. of fa Shoe jack. At the base of the last pin is a shoulder or last block which is engaged-by the crown of the last to support it. Vhenslices having high tops or uppers are being positioned upon such a support, the upper or lining or both are frequently caught between the crown of the last and the last block or the Shoulder of the last pin andl pinched therebetween when pressureris applied to the result that the upperis injured.

.An object of' this invention is to provide a novel Shoe supportv whichwillprevent such accidental pinching and consequent in-.p

jury to .the upper; Y

A feature of the"invention Consists in improved means for spreading theupper outwardly as the shoe last is pressed down upon the shoe support, which means may, comprise a jointed member' or toggle, ara.,

shown, a. plurality of jointed members or toggles connected at their upper ends to a member arranged to Yslide upon the last pin,

the said toggles being pivoted at their lower ends to the upper'portion or last block Lof the last support or jack. Means isprovided to-maintain the toggles initially in a nearly. straight position so that vwhen pressure isy description when read in connection with the 'accompanying drawings and will Abe pointed out in the appended claims. Y

In the ,drawingso Y .y Figurel isV a view of the mechanism in verticalsection including also the shoe and last jpartly in Section; and ,Y

Fig. 2 is a perspective vView of the mechanismwith theshoe removed.

Referring to Fig'. 1 of the drawings, the numeral@ -indicates al last pin which has a conical portion4 seatedin the Lipper end or last block 5 of a Shoe support .orjaclnV The pin is held in positionby a latch l6 which eng-ages o a circumferential groove ,in the'porf tion 4. The portions Zand 4 are lo'oredflon'-YV gitudinally and lin the bore -is a spring 8 which rests atjits lower end onja screwl plug 10 threaded into the bore of the portion 4 at its lowerend. i At :its upper end, 'the springV 8 restsagainst a .rod 12 which lies in a transverse slot 14 :formed inthe pin 2. The rod 12 Ais rseated at its ends in 'ameniber'shown as a collar 16 which is varranged to slide longitudinally ofthe pin,2and is normally held by` thespring 8, in raised posi-` tion with the rod l2 against the 1upperzend. ofthefslot 14. Betweenthe collar 16`and thefupper end 5' of theshoe'supporti's ar? mese@ a Series of jointedY members er toegles 15, each one of which has itslower end pivoted to the portionV 5 and its upper lend pivote'd to the collar 16. These toggles are Y vor' such'length as to be close to the last pin Ibut in partly broken position when the collar 16 is raised and the rod 12V is at theV upper endv of the slot 14. Y Y

In the use of the illustrated mechanism, a

shoe upper is thrown over the pin'2, the

collar 16 `and the inclined upper portionsof the toggles ltending to spreadtheupper as the Shoe is brought down over the pin and the top of the pin located in the pin hole of the last. The last is then pressed downwardly against the collar 16 which is depressed against the spring 8. This causes the toggles 15 to bend outwardly, effecting a further and positive spreading of the shoe upper and preventing any possibility of the shoe upper being caught between the crown of the last and the collar 16.

This application is a division of our application Serial No."876,949, iledDecember 12, 191-1, which leventuated in United States Letters Patent No. 1,271,741, on July 9, 1918.

Having fully described our invention, what we claim as new and desire to secure by Letters Patent of the United States is:

1. A device of the class described including a last support, a last pin, and an upper spreading member comprising a member having a joint between its ends, arranged to be bent by pressure ofthe last and to force the upper outwardly to prevent catching of the upper between the last support and the last.

2. A device of the 'class described including a. last support, a last pin, a. member arranged to slide on the last pin, and jointed members connected at their upper ends to the sliding member and pivoted at their lower ends to the last support. I

3. A mechanism of the class described comprising a shoe support having a last pin, a toggle having its lower end pivoted to the support and having its upper end movably mounted relatively to the last pin, and means for yieldingly holding the toggle in a slightly bent position, the toggle being adapted to be bent outwardly by pressure of a last applied to its upper end when placed vupon the last pin.V

' f1. Ina mechanism of the class described, the combination with a last pin and a last support, of a collar slidingly mounted upon the last pin, and a seriesof toggles connected between the collar and the last support.

5. In a mechanism ofthe class described, the combination with a shoe support having a last pin, of ajmember movable vertically relatively to the last pin, a plurality of toggles having their ends pivoted respectively to the member and to the last support, and means for holding the toggles inl a slightly outwardly bent position and permitting the toggles to be bent outwardly when the member is depressed by pressure of a last placed upon the last pin.

6. A heel support for a last having, in combination, a last block, a last pin mounted upon the block, and upper spreading toggle members normally supported in close proximity to the last pin and arranged to bend outwardly away from the last pin positively to spread the upper as the shoe last is forced down on the last pin.

7. A heel support for a last having, in combination, a last block, a slotted last pin mounted upon the block, upper spreading toggle members constructed and arranged to be bent outwardly by pressure of the last, means engaging the slot in the last pin for limiting straightening movement of the toggles, and a spring tending to straighten the toggles.

8. A heel support for a last having, in combination, a last block, a spindle lfixed in the last block, spreading members jointed between vthe ends and pivotally mounted at their ends at each side of theblock, and an y actuating device for effecting outward bending'of the members at their'joints.

9. A heel support for a last having, in combination, a last block, a spindle fixed in the last block, aA member arranged to slide on the spindle, a plurality of jointed members pivoted at one end to the last block and at the other end to said sliding member, and means for normally holding the jointed members close to the spindle and arranged yieldingly to allow the olinted members to bend outwardly when pressure is applied to .the sliding member.

In testimony whereof I, the said ALBERT A. MAcLEoD, have signed my name to this specification.

In testimony whereof I, the said MAY E. BROWN, have signed my name to this specilication;
